Computer Sketch Recognition
<p>Tens of thousands of years ago, humans drew sketches that we can see and identify even today. Sketches are the oldest recorded form of human communication and are still widely used. The universality of sketches supersedes that of culture and language. Despite the universal accessibility of …

Combining representations for improved sketch recognition
Sketching is a common means of conveying, representing, and preserving information, and it has become a subject of research as a method for human-computer interaction, specifically in the area of computer-aided design. Digitally collected sketches contain both spatial and temporal information; …

3D Sketch Recognition Using The Microsoft Kinect
The concept of sketch-based recognition has recently been used to enhance object categorization and speed up image retrieval. However, in each of the previous studies, the user was required to sketch on a two-dimensional plane. Currently there haven’t been any studies on the performance of …

Sketch recognition for Course of Action diagrams
… Course of Action diagrams. User input is through sketching, or a combination of sketching and speech. Course of Action symbols are recognized incrementally, and the informal sketching input is replaced with formal images of the symbols. The system uses the LADDER shape definition language to …

Natural error correction techniques for sketch recognition
… it very easy for users to input information by sketching as if on paper. In addition, sketch recognition systems help users convert these sketches into information that the computer understands. While lots of work has been done in developing better sketch recognizers, very little work has …

Building an electronic drafting table for sketch recognition
Sketch recognition as developed by the CSAIL Design Rationale Group allows a designer to sketch out and test design ideas without the need for complicated CAD programs. An electronic drafting table is required to capture large designs. The design of the electronic drafting table in this thesis uses …

LADDER : a perceptually-based language to simplify sketch recognition user interface development
Diagrammatic sketching is a natural modality of human-computer interaction that can be used for a variety of tasks, for example, conceptual design. Sketch recognition systems are currently being developed for many domains. However, they require signal-processing expertise if they are to handle the …

Understanding freehand diagrams : combining appearance and context for multi-domain sketch recognition
… diagrams. We present a novel framework for sketch recognition that seamlessly combines a rich representation of local visual appearance with a probabilistic graphical model for capturing higher level relationships. This joint model makes our system less sensitive to noise and drawing …

Envisioning sketch recognition : a local feature based approach to recognizing informal sketches
Hand drawn sketches are an important part of the early design process and are an important aspect of creative design. They are used in many fields including electrical engineering, software engineering and web design. Recognizing shapes in these sketches is a challenging task due to the imprecision …

Drawing on the World: sketch in context
This thesis introduces the idea that combining sketch recognition with contextual data-information about what is being drawn on-can improve the recognition of meaning in sketch and enrich the user interaction experience. I created a language called StepStool that facilitates the description of the …

User-directed sketch interpretation
… and object diagrams) by combining an off-line sketch recognition system with the user interface of a traditional structured graphics editor. The system, called UDSI (user-directed sketch interpretation), aims to provide drawing freedom by allowing the user to sketch entirely off-line using a …

Sketch interpretation using multiscale stochastic models of temporal patterns
Sketching is a natural mode of interaction used in a variety of settings. For example, people sketch during early design and brainstorming sessions to guide the thought process; when we communicate certain ideas, we use sketching as an additional modality to convey ideas that can not be put in …

Interpretation of box-and-point diagrams in classroom learning partner
… interpreter was designed to use state of the art sketch recognition tools to recognize shapes, and state of the art text recognition tools to recognize text. The results of each are then combined to interpret the meaning of the diagram.

ICEMENDR : intelligent capture environment for mechanical engineering drawing
… for recognizing simple mechanical engineering sketches. This involves the analysis of complex mechanical engineering parts and their components and consists of creating a hierarchical recognition system capable of parsing these parts with simpler geometric primitives. The system seeks to …

Paper Dreams : an adaptive drawing canvas supported by machine learning
… ideas. Paper Dreams is a web-based canvas for sketching and storyboarding, with a multimodal user interface integrated with a variety of machine learning models. By using sketch recognition, style transfer, and natural language processing, the system can contextualize what the user is drawing; …
